In recent years, heat storage deodorization devices have become popular, but do they really meet production needs? When it comes to deodorization devices, there are various treatment methods available. Among the combustion methods, which have the highest purification rates, more companies are choosing the "catalytic type," which has operating costs less than half that of direct combustion, requires less space than heat storage types, has shorter lead times, and lower installation costs. As fuel costs rise, the advantages of catalytic deodorization devices, which can reduce fuel consumption and maintenance costs, are becoming increasingly prominent. Compared to heat storage types, these devices are smaller and have quicker startup times, making them ideal for production lines that do not operate 24 hours, test plants, and research and development use. Therefore, we are offering a set of three documents that explain the features of catalytic deodorization devices! Please take a look as reference material for your introduction considerations. Additionally, feel free to consult us regarding VOC measures or any odor-related issues. 【Overview of the 3-Book Set】 ■ Comprehensive Product Catalog (Includes our deodorization devices from heat storage to catalytic types) ■ Basic Knowledge for Introducing VOC Treatment Devices (Includes information on emission regulations and how to choose devices) ■ Comparison Table of Deodorization Methods (Comparison with combustion, plasma, adsorption, etc.) *You can view them immediately from "Download."

• Air conditioning equipment

The "catalytic deodorization device" is a system that facilitates the oxidation reaction by bringing combustible substances, VOCs, and odors in exhaust gas into contact with air through a catalyst, resulting in odorless and harmless emissions. Since it can initiate the oxidation reaction at low temperatures (300°C to 350°C) below the ignition point, it consumes about one-third of the fuel compared to direct combustion deodorization devices for preheating. Additionally, it is equipped with a built-in heat exchanger, and by adding a secondary heat exchanger, significant fuel savings can be achieved. 【Features】 ■ High deodorization efficiency with high-performance platinum-based catalysts ■ Low generation of nitrogen oxides, enabling low NOx operation ■ Negative pressure structure in the exhaust gas flow path within the device to prevent odor leaks ■ Integrated structure with low flow resistance, designed to minimize power consumption *For more details, please refer to the PDF materials or feel free to contact us.

**[Problems Faced by Company B]** There were ongoing concerns from nearby residents about odors leaking from the factory. The source of the odor was VOC gases generated during the resin molding process. Although a treatment system had already been installed, the new production line made it difficult to keep up with the processing, leading to considerations for adding another treatment system. However, a fundamental issue arose: there was nowhere to install it, including the work space. Installing it outside the building was also considered, but that was not possible due to regulations such as the green space law. **[Implementation Effects]** By suspending the system from the ceiling, there were no issues with floor space. Additionally, it was equipped with a function to utilize exhaust heat to warm the workspace during winter. VOC treatment was achieved in a compact space, and energy savings were also realized. Our customers were satisfied. ● For more details, please download the catalog or contact us.

**[Issues Faced by Company A]** They were concerned about the deterioration of the workplace environment for employees due to VOCs generated during the drying process of resin product molding and coating. While combustion-type treatment devices are the most effective for VOC treatment, they struggled to find a device that met the condition of not threatening the 1.5m wide workspace between the dryers. Even when devices that could fit in the space were available, they often lacked sufficient processing capacity, causing them distress. **[Implementation Effects]** The compact catalytic deodorization device, which is easy to operate with a touch panel, achieved a space-saving design of 120cm in width, 50cm in depth, and 70.5cm in height, while providing a processing capacity of over 3N?/min and a VOC removal efficiency of over 98%. After installation, the solvent odor that had been lingering in the workspace was reduced, creating a safer working environment. Employees have also provided high praise, stating that "it has become easier to work" and "the solvent odor no longer clings to clothing." ● For more details, please download the catalog or contact us.

TESSHA' s Catalytic Oxidizer is a thermal recuperative and has a built-in heat exchanger. This built-in heat exchanger preheats the incoming contaminated gas by utilizing heat from the clean diThis system is based on the simplest technology to destruct VOCs. A Direct Fired Thermal Oxidizer introduces the VOCs gas and/or malodorous gas into a fire-box through or near the burner and retains the gas for approximately 1 second at high temperatures of 700°C to 800°C to get enough VOCs destruction.

This type of system is very effective and suitable for the case of purifying large gas flows with low VOCs density. The gas is fed into an absorption segment of a concentrator and flows longitudinally through a rotor which contains a filter with an absorption media and is continuously rotating. The VOCs are absorbed by the media and cleaned gas is directed to an outlet chimney and released into the atmosphere. The media continue absorbing VOCs with rotation of the rotor and get saturated.

If too many carbon particles adhere to the demister, it may cause clogging, leading to an abnormal increase in back pressure, which could result in engine overheating or damage to the wire demister. Please pay close attention to maintenance management. 【Maintenance Management】 - Regularly (every 5 to 10 days of operation) remove the cleaning plug, and while the filter is installed, run the engine at idle to discharge the accumulated carbon into a collection bag or similar. - It is also acceptable to use a vacuum cleaner for cleaning. The demister should be inspected at the start of each work session; pull out the demister and either shake off the carbon or soak it in a neutral detergent solution to clean off the adhering carbon. - Inspect the main body, inlet pipe, outlet pipe, and brackets for cracks. - Be careful not to inhale carbon particles during work. ● For more details, please contact us.
